MAGNETIC ALIGNMENT ELEMENTS FOR CON- TINUOUS FORM T YPEWRITERS OR MACHINES Mark Wexler, Minneapolis, Minn.

Application December 27, 1954, Serial No. 477,630

2 Claims. (Cl. 197-142) My invention relates to gauges and/ or guides for continuous or other elongated paper forms used in typewriters, and more particularly to relatively inexpensive devices of this character which may be readily positioned on the machines in operative position, and removed therefrom.

It is wellknown that in continuous-form typewriting, particularly when multiple copies are being typed, that the forms, after having left the typewriter, tend to create a drag or resistance upon the carriage during the reciprocal lateral movements of the latter. This drag or resistance tends to cause angular shifting movements to be imparted to the form within the machine, with the consequent misalignment of the typewritten material. Frequent stopping of the machine and realignment of the form therein is, therefore, necessary with a resultant loss of time. Also, untidiness of the forms frequently results from the multiplicity of erasures necessitated.

The primary object of my invention is the provision of relativly small, lightweight, and inexpensive paper gauges and/or guides for typewriters utilized in connection with continuous forms and the like, which may be readily and detachably secured to the carriages of said typewriter at the opposite edges of the continuous forms therein, whereby to cause said forms to resist the lateral forces due to the drag exerted thereon by the reciprocal movements of the carriage.

A still further object of my invention is the provision of devices of the class above described, which include magnetic heads which, at least in part, tend to retain said guide-acting gauges in a desired set position upon the metallic paper table or other metallic part of the typewriter carriage.

A still further object of my invention is the provision of a device of the class immediately above described which further includes a pressure-sensitive adhesive layer on the bottom surface of said magnetic head to further aid in securing the guide-acting gauges in desired set positions.

A still further object of my invention is the provision of a device of the class above described, which includes opposed, preferably non-metallic, tongues adapted to overlie the adjacent edge portions of the forms whereby to prevent vertical separation of the superimposed forms during reciprocation of the carriage.

The above and still further objects of my invention will become apparent from the following detailed specification, appended claims, and attached drawings.

Referring to the drawings wherein like characters indicate like parts throughout the several views Fig. 1 is a perspective view of a continuous form typewriter having my novel guide-acting gauges secured to the paper table thereof;

Fig. 2 is an enlarged view in perspective of one of my novel guide-acting gauges;

Fig. 3 is a view in top plan of the structure of Fig. 2; and

2,802,558 Patented Aug. 13, 1957 Fig. 4 is an enlarged fragmentary sectional view taken substantially on the line 4-4 of Fig. 1.

Referring with greater particularity to the drawings, the numeral 1 indicates in its entirety a conventional typewriting machine, the carriage of which is identified by the numeral 2. Carriage 2 includes the platen 3, the paper table 4 immediately there-behind, and the paper bail 5. Paper table 4 isp referably formed from ferrous metal.

As shown in Fig. 1, a continuous form 6, having multiple copies 6a, is operatively positioned within the typewriter 1, with the trailing end 7 on the platen 3, the intermediate portion 8 overlying the paper table 4 and the leading end 9 passing rearwardly and downwardly from the typewriter 1, and accumulating there-below on any suitable support or receptacle, not shown.

Quite obviously, as the carriage 2 is reciprocated, the accumulated leading end 9 of the continuous form 6 tends to resist such movements. This drag or resistance imparts a twisting action upon the trailing end 7, which, as above explained, causes the trailing end 7 of the form 6 between the platen 3 and the paper bail 5 to be twisted from its desired path of travel, to wit, at right angles to the platen 3. In order to prevent this undesirable twisting of the form 6, I provide guide-acting gauge elements, identified in their entirety by the numeral 10, and comprising block-like metallic heads 11 having parallel upper and lower surfaces 12 and 13 respectively. As shown,

, particularly in Fig. 4, the tongues 14 are secured by any suitable means to the upper surfaces 12 and project laterally outwardly therefrom, for a purpose which will hereinafter become apparent. Secured to the lower surface 13 of the heads 11 is a layer of pressure-sensitive adhesive 15. Any well-known pressure-sensitive adhesive such as used on Scotch tape produced by Minnesota Mining and Manufacturing Company, may be utilized to provide the layer 15. For the purpose of facilitating removal and renewal of the layer 15, a conventional tape having pressure-sensitive adhesive on its opposite surfaces may be utilized.

As shown in Figs. 1 and 4, my novel guide-acting gauges 10 are positioned on the metallic paper table '4 immediately adjacent the opposite side edges 16 of the form 6. It will be noted that the tongues 14 overlie the opposite edge portions 16 of the form 6 and prevent vertical separation of the superimposed copies 6a during reciprocal movements of the carriage 2. The combined action of the magnetic heads 11 and the pressure-sensitive coatings 15 adequately anchor the gauge elements 10 in their desired position with their opposed faces 17 in sliding engagement with the opposite side edge portions 16 of the form 6. Neither the magnetic heads 11 nor the pressure-sensitive layer 15 is adequate for the purpose.

Preferably the tongues 14 are formed from relatively heavy paper stock so as to facilitate imprinting of advertising material on the upper surfaces 18. Also, such paper stock is relatively inexpensive, is light in weight and precludes any undesirable friction therebetween and the overlying side edge portions 16 of the form 6 in the passage of the latter over the metallic paper table 4.

My invention has been thoroughly tested and found to be completely satisfactory for the accomplishment of the above objects, and while I have disclosed a preferred embodiment thereof, I wish it to be understood that same is capable of modification without departure from the scope of the appended claims.

What I claim is:

1. A paper gauge and guide for typewriters comprismg, a pair of magnetic heads adapted to be removably positioned in laterally spaced relationship to the ferrous metallic paper table of a typewriter adjacent opposite side edges of a continuous form mounted therein, said heads having substantially parallel upper and lower surfaces, the lower surface of said heads having a coating of pressuresensitive adhesive applied thereto, and the upper surface of said heads having tongues applied thereto which are adapted to overlie the adjacent side edges of said continuousrforrn in opposed relationship.

" ZQThestIuctureYdefined in claim 1 in which said tongues are formed from non-metallic material.
